## Description

An ESource (or "data source") is a description of a file or network location where data can be obtained (such as a mail account), or a description of a resource at that location (such as a mail folder).

In more concrete terms, it's an interface for a key file. All such key files have a main group named [Data Source]. The keys in a [Data Source] group map to GObject properties in an ESource.

Additional groups in the key file are referred to as "extensions". ESourceExtension serves as the base class for writing interfaces for these additional key file groups. The keys in one of these key file groups map to GObject properties in some custom subclass of ESourceExtension which was written specifically for that key file group. For example, a key file might include a group named [Calendar], whose keys map to GObject properties in an extension class named ESourceCalendar.

Each ESource contains an internal dictionary of extension objects, accessible by their key file group name. `e_source_get_extension()` can look up extension objects by name.

An ESource is identified by a unique identifier string, or "UID", which is also the basename of the corresponding key file. Additional files related to the ESource, such as cache files, are usually kept in a directory named after the UID of the ESource. Similarly, the password for an account described by an ESource is kept in GNOME Keyring under the UID of the ESource. This makes finding these additional resources simple.

Several extensions for common information such as authentication details are built into libedataserver (ESourceAuthentication, for example). Backend modules may also define their own extensions for information and settings unique to the backend. ESourceExtension subclasses written for specific backends are generally not available to applications and shared libraries. This is by design, to try and keep backend-specific knowledge from creeping into places it doesn't belong.

As of 3.12, an ESource with an ESourceProxy extension can serve as a GProxyResolver. Calling `g_proxy_resolver_is_supported()` on an ESource will reflect this constraint. Attempting a proxy lookup operation on an ESource for which `g_proxy_resolver_is_supported()` returns `FALSE` will fail with `G_IO_ERROR_NOT_SUPPORTED`.

## Functions

### E_SOURCE_PARAM_SETTING

    #define E_SOURCE_PARAM_SETTING (1 << G_PARAM_USER_SHIFT)

Extends GParamFlags to indicate the GObject property is associated with a key file value. Use this flag when installing GObject properties in ESourceExtension subclasses.

Since: 3.6

### e_source_new ()

    ESource *
    e_source_new (GDBusObject *dbus_object,
                  GMainContext *main_context,
                  GError **error);

Creates a new ESource instance.

The “changed” signal will be emitted from `main_context` if given, or else from the thread-default GMainContext at the time this function is called.

The only time the function should be called outside of ESourceRegistry is to create a so-called "scratch" ESource for editing in a Properties window or an account setup assistant.

FIXME: Elaborate on scratch sources.

#### Parameters

dbus_object | a GDBusObject or `NULL`. | [allow-none]
main_context | a GMainContext or `NULL`. | [allow-none]
error | return location for a GError, or `NULL` |

#### Returns

a new ESource, or `NULL` on error

                           GError **error);

Creates a new "scratch" ESource with a predetermined unique identifier.

The “changed” signal will be emitted from `main_context` if given, or else from the thread-default GMainContext at the time this function is called.

#### Parameters

uid | a new unique identifier string |
main_context | a GMainContext or `NULL`. | [allow-none]

a hash value for `source` .

Since: 3.6

### e_source_equal ()

    gboolean
    e_source_equal (ESource *source1,
                    ESource *source2);

Checks two ESource instances for equality. ESource instances are equal if their unique identifier strings are equal.

#### Parameters

source1 | the first ESource |

Identifies the parent of `source` by its unique identifier string. This can only be set prior to adding `source` to an ESourceRegistry.

The internal copy of “parent” is automatically stripped of leading and trailing whitespace. If the resulting string is empty, `NULL` is set instead.

#### Parameters

parent | the UID of the parent ESource, or `NULL`. | [allow-none]

Since: 3.6

### e_source_get_enabled ()

    gboolean
    e_source_get_enabled (ESource *source);

Returns `TRUE` if `source` is enabled.

An application should try to honor this setting if at all possible, even if it does not provide a way to change the setting through its user interface. Disabled data sources should generally be hidden.

This function does not take into account `source`'s ancestors in the ESource hierarchy, each of which have their own enabled state. If any of `source`'s ancestors are disabled, then `source` itself should be treated as disabled. Use `e_source_registry_check_enabled()` to easily check for this.

#### Parameters

source | an ESource |

#### Returns

whether `source` is enabled

Since: 3.6

### e_source_set_enabled ()

    void
    e_source_set_enabled (ESource *source,
                          gboolean enabled);

Enables or disables `source` .

An application should try to honor this setting if at all possible, even if it does not provide a way to change the setting through its user interface. Disabled data sources should generally be hidden.

#### Parameters

#### Parameters

source | an ESource |

#### Returns

whether `source` is writable

Since: 3.6

### e_source_get_removable ()

    gboolean
    e_source_get_removable (ESource *source);

Returns whether the D-Bus service will allow `source` to be removed. If `source` is not writable, calls to `e_source_remove()` will fail.

#### Returns

whether `source` is removable

Since: 3.6

### e_source_get_remote_creatable ()

    gboolean
    e_source_get_remote_creatable (ESource *source);

Returns whether new resources can be created on a remote server by calling `e_source_remote_create()` on `source` .

Generally this is only `TRUE` if `source` has an ESourceCollection extension, which means there is an ECollectionBackend in the D-Bus service that can handle create requests. If `source` does not have this capability, calls to `e_source_remote_create()` will fail.

#### Parameters

source | an ESource |

#### Returns

whether `source` can create remote resources

Since: 3.6

### e_source_get_remote_deletable ()

    gboolean
    e_source_get_remote_deletable (ESource *source);

Returns whether the resource represented by `source` can be deleted from a remote server by calling `e_source_remote_delete()`.

Generally this is only `TRUE` if `source` is a child of an ESource which has an ESourceCollection extension, which means there is an ECollectionBackend in the D-Bus service that can handle delete requests. If `source` does not have this capability, calls to `e_source_remote_delete()` will fail.

#### Parameters

source | an ESource |

#### Returns

whether `source` can delete remote resources

Since: 3.6

### e_source_get_extension ()

    gpointer
    e_source_get_extension (ESource *source,
                            const gchar *extension_name);

Returns an instance of some ESourceExtension subclass which registered itself under `extension_name` . If no such instance exists within `source` , one will be created. It is the caller's responsibility to know which subclass is being returned.

If you just want to test for the existence of an extension within `source` without creating it, use `e_source_has_extension()`.

Extension instances are owned by their ESource and should not be referenced directly. Instead, reference the ESource instance and use this function to fetch the extension instance as needed.

#### Parameters

source | an ESource |
extension_name | an extension name |

#### Returns

an instance of some ESourceExtension subclass.

                                  gpointer user_data);

Asynchronously calls the InvokeAuthenticate method on the server side, thus the backend knows what credentials to use to connect to its (possibly remote) data store.

When the operation is finished, `callback` will be called. You can then call `e_source_invoke_authenticate_finish()` to get the result of the operation.

#### Parameters

source | an ESource |
credentials | an ENamedParameters structure with credentials to use; can be `NULL` to use those from the last call. | [allow-none]
cancellable | optional GCancellable object, or `NULL`. | [allow-none]
callback | a GAsyncReadyCallback to call when the request is satisfied |
user_data | data to pass to the callback function |

### e_source_invoke_credentials_required_sync ()

    gboolean
    e_source_invoke_credentials_required_sync
                                   (ESource *source,
                                    ESourceCredentialsReason reason,
                                    const gchar *certificate_pem,
                                    GTlsCertificateFlags certificate_errors,

                                    GError **error);

Let's the client-side know that credentials are required. The `reason` defines which parameters are used. The client passed the credentials with an `e_source_authenitcate()` call.

The `E_SOURCE_CREDENTIALS_REASON_REQUIRED` is used for the first credentials prompt, when the client can return credentials as stored from the previous success login.

The `E_SOURCE_CREDENTIALS_REASON_REJECTED` is used when the previously used credentials had been rejected by the server. That usually means that the user should be asked to provide/correct the credentials.

The `E_SOURCE_CREDENTIALS_REASON_SSL_FAILED` is used when a secured connection failed due to some server-side certificate issues.

The `E_SOURCE_CREDENTIALS_REASON_ERROR` is used when the server returned an error. It is not possible to connect to it at the moment usually.

If an error occurs, the function sets `error` and returns `FALSE`.

#### Parameters

source | an ESource |
reason | an ESourceCredentialsReason, why the credentials are required |
certificate_pem | PEM-encoded secure connection certificate, or an empty string |
certificate_errors | a bit-or of GTlsCertificateFlags for secure connection certificate |
op_error | a GError with a description of the previous credentials error, or `NULL`. | [allow-none]
cancellable | optional GCancellable object, or `NULL`. | [allow-none]
error | return location for a GError, or `NULL`. | [allow-none]

#### Returns

`TRUE` on success, `FALSE` on error

### e_source_connection_status_get_type ()

    GType
    e_source_connection_status_get_type (void);

## Types and Values

### E_SOURCE_CREDENTIAL_USERNAME

    #define E_SOURCE_CREDENTIAL_USERNAME "username"

A name of the named parameter used for usernames in credentials, used to authenticate users with `e_source_invoke_authenticate_sync()` and `e_source_invoke_authenticate()`. The named parameter is optional, different authentication methods can use different names.

Since: 3.16

### E_SOURCE_CREDENTIAL_PASSWORD

    #define E_SOURCE_CREDENTIAL_PASSWORD "password"

A name of the named parameter used for passwords in credentials, used to authenticate users with `e_source_invoke_authenticate_sync()` and `e_source_invoke_authenticate()`. The named parameter is optional, different authentication methods can use different names.

Since: 3.16

### E_SOURCE_CREDENTIAL_SSL_TRUST

    #define E_SOURCE_CREDENTIAL_SSL_TRUST "ssl-trust"

A name of the named parameter used for SSL trust in credentials, used to authenticate users with `e_source_invoke_authenticate_sync()` and `e_source_invoke_authenticate()`. The named parameter is optional. Its value corresponds to current ESourceWebdav::ssl-trust property, in case the ESource has that extension available. This is required to have up-to-date data on the server side, when the client side just saved the SSL trust change, which might not be propagated into the server (factory) side quickly enough. The key is added into the credentials in `invoke_authneticate()` automatically, if the corresponding ESource contain a WebDAV extension and the key is not part of the credentials already.

### enum ESourceConnectionStatus

Connection status codes used by the ESource to indicate its connection state. This is used in combination with authentication of the ESource. For example, if there are multiple clients asking for a password and a user enters the password in one of them, then the status will change into 'connecting', which is a signal do close the password prompt in the other client, because the credentials had been already provided.

#### Members

E_SOURCE_CONNECTION_STATUS_DISCONNECTED | The source is currently disconnected from its (possibly remote) data store. |
E_SOURCE_CONNECTION_STATUS_AWAITING_CREDENTIALS | The source asked for credentials with a 'credentials-required' signal and is currently awaiting for them. |
E_SOURCE_CONNECTION_STATUS_SSL_FAILED | A user rejected SSL certificate trust for the connection. |
E_SOURCE_CONNECTION_STATUS_CONNECTING | The source is currently connecting to its (possibly remote) data store. |
E_SOURCE_CONNECTION_STATUS_CONNECTED | The source is currently connected to its (possibly remote) data store. |
